Signal
Condition
Power fuse
Verify that the LED on the rectifier card is switched off
[Figure7-18]
Chart microswitch
Verify that the power supply carriage is perfectly attached to the
bottom and that pushes the microswitch [Figure 7-17 b)]
Magneto-thermic chart Switch
Verify that the switch is on position I [Figure 7-17 a)]
Control signals connectors
Verify that the plug is connected in the right way [Figure 7-18]
Command coils connector
Verify that the plug is connected in the right way [Figure 7-18]
Three-phase power connector
Verify that the plug is connected in the right way [Figure 7-17 a)]
Note that the handle on the left side of the connector has to be
pulled toward the front of the transmitter to block the connector in
its place.
7.3.4 Control card
The functions of this microprocessor card are the following :
• Protection of the power supply section
• Communication with the control unit
• Analog parameters measurement
The card is installed in the rack under the RF modules site, in a metallic box where
it's included the control card of RF combiner [Figure 7-18 a)]. This card needs two
analogic tunings : air input temperature and Bus DC voltage (not stabilized). For the
tuning use the Power Supply menu of the control unit and identify the appropriate
trimmers in Figure [7-18 b)].
All the input digital signals are of "PNP" type, the common power supply is 12Vdc;
the line of 12 Vdc is protected against the ground short circuit through a self-restoring
fuse (ptc). An possible short circuit on this supply will cause trip the machine. Eventual
messages of fault in corrispondence of a short circuit on this line won't be valid.
To restore the supply is necessary to remove the short circuit condition and switch
OFF the equipment for about a minute in order to let the fuse self-restore.
7.3.5 Interface Board
The control card of the power supply is connected with the actuators through an
interface board [Figure 7-19].
All the output signals from the control card are interfaced through power relays and
signal relays. On the relay coils a signalling LED is present and indicates the command
status on the control unit: the LED turned ON indicates that the coil is excited. All the
power contacts are equipped with noise suppressing network.
The feeding of the relay is supplied from a line protected against the short circuit
through self-reloading ground protections.
